Gymnastics is a demanding sport that places unique forces on the upper extremity. https://www.selleckchem.com/products/Nanchangmycin.html The repetitive nature of the sport and the high-impact forces involved may predispose the gymnast to overuse injuries. Risk factors for injuries in gymnastics are not well understood.
The purpose of this study was to ascertain whether preseason upper extremity range of motion (ROM) and strength differ between National Collegiate Athletic Association (NCAA) Division I collegiate gymnasts who sustain an in-season upper extremity injury and those who do not. We hypothesized that gymnasts who sustain an upper extremity injury would demonstrate reduced ROM and strength compared with noninjured gymnasts.
Cohort study; Level of evidence, 3.
Over 4 seasons, from 2014 to 2018, a total of 15 female NCAA Division I collegiate gymnasts underwent preseason upper extremity ROM (shoulder flexion, internal and external rotation; elbow extension; wrist extension) and strength (shoulder internal and external rotation, and middle and lowere the unique features and requirements of gymnastics. Further, it may be challenging to discern differences in clinical measures of ROM and strength in gymnastics populations owing to the bilateral nature of the sport.
Preseason upper extremity ROM and strength were not different between gymnasts who sustained an in-season upper extremity overuse injury and those who did not. It is possible that ROM and strength measures used to screen other overhead athletes may not capture the unique features and requirements of gymnastics. Further, it may be challenging to discern differences in clinical measures of ROM and strength in gymnastics populations owing to the bilateral nature of the sport.Rugby is the fastest growing team sport in the United States for male and female athletes. It is a contact/collision sport with an injury risk profile that includes concussions.
To examine the prevalence of concussions in male and female rugby players in the United States and to characterize behaviors around reporting concussions that could be a target for prevention and treatment efforts.
Cross-sectional study; Level of evidence, 3.
An online survey distributed to active members on the USA Rugby membership list was used to examine self-reported concussions in male and female athletes. Concussion-reporting behaviors and return to play after a concussion were also explored. Statistical analysis was used to compare male with female athletes and report differences, with years of experience as a dependent variable.
The proportion of athletes with a history of at least 1 concussion was 61.9% in all respondents. Of those who reported a concussion, 50.8% reported the concussion during the game or practice -to-play protocols are necessary in the US rugby union population.
US rugby union athletes may not report concussions to medical personnel or follow return-to-play protocols guided by medical advice. This could result from a lack of education on concussion recognition and the risks associated with continued play after a concussion as well as limited access to health care. Further education efforts focusing on the identification of concussions, removal from play, and return-to-play protocols are necessary in the US rugby union population.The correlation between isokinetic internal and external rotation (IR and ER) strength and functional outcomes in patients with anterior shoulder instability treated by arthroscopic capsulolabral reconstruction (ACR) has not been studied.
To analyze isokinetic IR and ER strength and their correlation with clinical outcomes in patients with anterior shoulder instability treated by ACR.
Case series; Level of evidence, 4.
Between January 2004 and June 2015, a total of 104 patients who underwent ACR for anterior shoulder instability were analyzed. The mean peak torque (PT) in IR (IR) and ER (ER), PT deficit (PTD; %) relative to the opposite healthy shoulder, and PT ratio (PTR; ER/IR) were calculated before and 1 year after surgery. Functional scores were evaluated before surgery and at every follow-up visit. Recurrence and postoperative apprehension during ER at 90° of arm abduction were evaluated at 1 year and the final follow-up (76.6 ± 64.4 months).
IR and ER strength were measured for 68 of 1 year (= .022).
For those with anterior shoulder instability, preoperative IR and ER strength of the involved shoulder were lower than those of the uninvolved shoulder. IRrecovered, whereas ERremained weak after ACR. To prevent positive apprehension after surgery, IR and ER strengthening exercises are important, with more emphasis on exercises for ER.

However, there remains a limited body of literature examining the effect of depression on outcomes after anterior cruciate ligament reconstruction (ACLR).
The primary purpose of this study was to compare postoperative function patient-reported outcome scores between patients with and patients without preoperative depression symptoms undergoing ACLR. Secondary goals included comparing postoperative pain interference and depression scores between the 2 groups.
Cohort study; Level of evidence, 2.
In this single-center retrospective cohort study, pediatric and adult patients who underwent ACLR were included. The Physical Function (PF), Pain Interference (PI), and Depression (D) domain scores of the Patient-Reported Outcomes Measurement Information System (PROMIS) were collected preoperatively and at 6 and 12 months postoperatively. Patients were separated into clinicafference values, in PROMIS-PF scores at 12 months after ACLR, regardless of the presence of preoperative depression symptoms. These data suggest that having depression symptoms preoperatively does not significantly hinder a patient's recovery after ACLR.
There was a significant improvement, which exceeded currently accepted minimal clinically important difference values, in PROMIS-PF scores at 12 months after ACLR, regardless of the presence of preoperative depression symptoms. These data suggest that having depression symptoms preoperatively does not significantly hinder a patient's recovery after ACLR.
